NodeFilesystemAlmostOutOfSpace #
Meaning #
This alert is similar to the NodeFilesystemSpaceFillingUp alert, but rather
than being based on a prediction that a filesystem will become full in a certain
amount of time, it uses simple static thresholds. The alert will fire as at a
warning level at 5% space left, and at a critical level with 3% space left.
Impact #
A node’s filesystem becoming full can have a far reaching impact, as it may cause any or all of the applications scheduled to that node to experience anything from performance degradation to full inoperability. Depending on the node and filesystem involved, this could pose a critical threat to the stability of the cluster.
